Abstract: The pollution of livestock excrement and the shortage of feed resources have become two major problems that need to be solved urgently in the current breeding industry. At present, the biological processing technologies for livestock excrement can no longer meet the requirements of developing low-carbon animal husbandry advanced as the development of modern agriculture in our country. Hermetia illucens, as one of the effective insects for transformation of livestock excrement, which can not only realize the harmless treatment and resource utilization of livestock excrement, but also reduce the environmental pollution caused by the excrement. Meanwhile, the H. illucens larvae or prepupae can be used as animal protein feed, and the frass as organic fertilizer. Therefore, the H. illucens has the advantage in realizing lowcarbon animal husbandry. The application researches of H. illucens in pig and chicken breeding, forage grass planting, and reducing the pollution of livestock excrement were expounded to provide theoretical basis for the further development of lowcarbon animal husbandry mediated by H. illucens.
